WIND-ENGINE'.

SPECIFICATION forming' part of Letters .Patent No. 225,539, dated March 16, 1880. Application filed September 15, 1879.

To all 'whom it may concern Be it known that 1, RANsoM E. STRAIT, of Galesburg, county of Kalamazoo, State of Michigan, have invented new and useful Improvements in Windmills, of which the following is a specification.

The object of my invention is the construction and arrangement of a large vane, located at right angles with the wheel-shaft, in connection with a smaller vane operating the larger by meansof semi-elliptic beveled cogwheels, by which arrangement the vane will be more substantial and the mill-wheel be more readily adapted to the changes of the wind.

In the accompanying drawings, Figure l is a perspective view of my invention 5 Fig. 2, a' longitudinal section on the line of the wheelshaft; Fig. 3, the large vane. Fig. 4 shows beveled wheels between the cap and head; Fig. 5, face view of wheel showing degree of bevel, and Fig. 6 side view of wheel.

A is the cap, resting on standards or frame P P, having a raised center' beveled on top, forming .a track for the wheels C C, which wheels are beveled on their rims from their outer face inclining to the rearward face to correspond with the track on which they rest, said wheels G C being without axles, as seen in Fig. 4. y

cl is the mill-head. into which is chilled, or cast with it, a pipe extending down through the cap A. This headdalso has a downwardly-inclined rim surrounding the wheels C C, which holds them in place and protects them from the weather, the portion of said head which restson the Wheels being also beveled to correspond with their form. By this arrangement the oil and wear of the parts will work itself out,`fallin g on the cap`A, instead of remaining among the wheels to clog them.

B is the large vane, secured to rod vor shaft B, said rod being attached to a beam, D, in a A,ening the same.

manner that will allow of its revolving, said beam D being secured to the mill-head at right angles with the wheel-shaft and extending to` near the center of vane B, thereby strength- (Shown in Fig. 3.)

It is designed -to cast this beam of iron, of such a size that it will balance the mill.

E and F are the semi-elliptic wheels of the beveled gearing, engaging the small vane H with the large vane B. These wheelsE and F may differ and vary in size.

e is the crankrod connecting the pitman f with the crank c of the wheel-shaft, said pitman f being shouldered to clear the crank c, and running in a slot on top portion of arm G, and extending down through the hollow tube to pump or machinery below.

W is the usual balance-ball or weight, and L the arm,l to which connection is made from below to fasten the mill out of gear.

When the wheel S is running the vane B rests horizontally, as shown by dotted lines at B', Fig. 2, when the vane H, secured to a shouldered arm, stands at oblique angles with the wheel-shaft and near the inner surface of the rim ofthe wheel or ends of the slats, which are not shownin the drawings.

Should an adverse wind strike the vane H it would swing back, as in Fig. l, when the large vane would stand perpendicular, as seen at B, Fig. 2.

What I claim is- Vane B, secured to rod R, said rod R secured to beam D, as shown, all located in rear of wheel S at right angles with shaft of wheel S, vane H, and cog-gearing E F, all combined, constructed, and arranged as shown, for the purpose set forth.
